Is Boolean Null = False

[Anonymous]

As the subject suggests, does Marketo see a NULL value in a Boolean field as equal to "False"?

I'm trying to setup a smart list with rules to check for values on multiple Boolean fields but getting a lot of false positives which after review appears to the result of the boolean values of NULL being represented as "False".

Yes an empty boolean is interpreted as false -- they are in essence the same thing since a checkbox field is a true/false field where checked = true, unchecked = false.
